METHOD OF ASSOCIATING AND FOLDING PRINTED SHEETS.

SPECIFICATION forming part of Letters Patent No. 498,033, dated May 23, 1893.

Application filed January 9, 1888- Serial No. 260,176- (No model.)

.To an whom it may concern.-

Be it known that I, WALTER SCOTT, of Plainfield, in the county of Union and State of New Jersey, have invented an Improved Method of Associating and Folding Printed Sheets, of which the following is a specification.

In my patent No. 37 3,487, I have represented a press in which sheets of two different sizes can be brought together for folding the same, and the sheets are conveyed along adjacent to the edge of the folding blade and are moving parallel thereto.

In printing presses that have heretofore been made in which the folder comes across the web or sheet and hence is at rightangles t the direction of movement of the sheet, a second folded sheet has been carried in between the folding rolls by the act of folding a sheet transversely, but in this instance the momentum of the sheets aids in carrying the same in between the rolls, and in fact the sheets continue to move in the same direction both before and during the folding operation.

In presses such as shown in my aforesaid patent the sheets have to be arrested before folding and carried off at right angles to their previous movement. Hence it has been difficult to start the narrow width sheet and draw it into the folding rolls because the edge of such narrow width sheet has substantially coincided with the opening between the folding rolls and with the edge of the folding blade. In my improvement I bring the sheets tosheets are simultaneously started at right angles to their previous movement and carried into the folder without the register of the sheets becoming defective.

In the drawings I have represented by diagrams some of the ways in which the sheets of two different widths can be brought together. In these diagrams the sheets of full width are marked A. and the sheets of half width marked 13. and of double the respective widths A B. The folding rollers are represeted at 66. and the folding blade at 1.

In Fig. 1. the sheet B. of half width is brought into the folding apparatus in such a manner that it coincides with one half of the full width sheet A. so that when the fold is made by the blade carrying the sheets in between the rollers 66. the fold in the sheet A. will coincide with one edge of the sheet B. and the sheet B. will be brought outside of the folds of the sheet A. This operation willbe the same whether the sheets A. and B. have been of double width as indicated in Fig. 2. and have been cut apart upon the line 62. or whether they have been only of the width shown in Fig. l.

In Fig. 3. I have represented two sheets A. with one sheet B. between them; the sheet B. coinciding with one half of each full width sheet A. and the fold has to be made by the blade 1. upon the line of the inner edge of the sheet B.

In Fig. 4. I have shown two sheets B. between two sheets A. the inner edges of the sheets B. being in line with the centers of the sheets A. so that the fold is made upon the line of the inner edges of the sheets B. and such sheets B. are inclosed between the sheets A. The sheet B. or B is usually inclosed between the sheet or sheets A. or A when folded and hence it is retained in place while subjected to subsequent folding operations and while being handled in binding or otherwise. Usually the sheets will be separated at the line 62. by a suitable cutter, the forms for printing being arranged in a proper manner so that the pages will come in the proper relative position, but if desired the sheets may remain uncut at the line 62. and be subjected to the folding operation at that line as indicated in Fig. 4.

My aforesaid patent illustrates the apparatus that may be made use of in printing, associatingand folding the sheets and it is not necessary to repeat herein a description of the construction of such apparatus. In all instances the sheets will be printed and.

brought together and imposed in the manner aforesaid, previous to the cutting or folding operation. My said press however is avai1- able for printing and delivering sheets in which the method of my present invention is VIS printed upon a press or presses of difierent.

construction from that set forth in my said patent.

a person skilled in the art to apply my inveniion under thedifferent conditions that may;

arise; and it will be observed that in consequence of disposing the sheet of greater Width' next the folding blade, so as toextend across: or bridge the faces of the folding rolls, and

disposing the sheet of narrower widthon' the opposite side of the wide sheet to the folding blade and with one -'edgesubstantial1y coineiding -with the openingbetween' the folding rolls, the wider sheet carries the edge of the narrower sheet in between the folding rolls; and this 'feature pe'rvades all'the various-arran geinents of the sheets described and represerited, whether the folding is upwardly or? downwardly, and the folding operations are not varied in consequence of the sheetsbeing cut apart or not.

I claim as my invention The method herein specified of associating and folding printed sheets which consists in I bringing the sheets into the folder adjacent The description'andillustrations will enable to the folding blade'and by a movement parallel with the folding blade and the edge of the narrower sheet substantially coincident to such blade and with a sheet of greater Width between the blade and the sheet of narrowerwidth,and-carrying-both sheets off at right angles to their previous movement by the blade acting "upon the sheet of greater width and carrying with it the edge of the sheet of less width' in 'between *snch folding rolls substantially as specified.

Signed by me'this 29th day of December, 1887.
